There's a small typo: if ($(':checked').length) === 0) {
should be: if ($(':checked').length === 0) {
If you use an editor like Visual Studio Code, you would see this error while you type. I make a lot of typos myself so it's a must feature for coding to me, you should test if it makes coding more easy to you too.
